How to choose among AI PDF tools

Scanned or image-only documents

Use OCR PDF or Scan to PDF first when the file is a scan, photo or image-only PDF. A searchable text layer makes summaries, chat and conversions more useful. The walkthrough to ask questions about a scanned PDF shows the OCR-then-chat flow end to end.

Long reading and research review

Use Summarize PDF for quick orientation, then Chat with PDF when you need follow-up questions about clauses, sections, definitions or evidence inside the document.

Quality checks before you download

  • Run OCR before AI analysis when text cannot be selected or searched in the original PDF.
  • Treat AI summaries as a reading aid and verify important facts against the source pages.
  • Use Compare PDF before signing or publishing when two versions of a document look similar but may contain revisions.

Best workflow

  1. Use OCR PDF first when the file is scanned or image-only.
  2. Use Summarize PDF or Chat with PDF to understand the document.
  3. Use Translate PDF, Compare PDF or PDF Question Generator when the next step is review, study or localization.

Common use cases

  • Ask questions about a long PDF instead of searching page by page.
  • Summarize a report or contract into key points.
  • Run OCR on scanned PDFs so text can be searched, copied or converted.

Specialized tools in this workflow

These focused tools solve narrower jobs that often sit between larger PDF workflows.
